摘　　要：基于区域海洋模型ROMS(Regional Ocean Modeling System)建立舟山群岛海域高分辨率潮汐、潮流模型,并采用实测潮汐、潮流观测资料对模型进行率定和验证,良好刻画了舟山海域潮波运动特征和规律。利用模拟结果对该海域潮流能大(小)潮涨急、落急功率密度分布以及有效利用时间、流向稳定性进行分析,并计算6条潮流能资源富集水道的蕴藏量和装机容量。结果表明:舟山群岛海域潮流能资源主要分布于螺头、西堠门、龟山航门等6处水道,大潮功率密度峰值超过25000 kW/m^(2),流向稳定系数大于0.95。大部分海域年发电小时数介于5000~7000 h,龟山航门、西堠门等水道年发电小时数超过5000 h。6处水道潮流能资源一类区面积7.77 km^(2),二类区面积41.99 km^(2),潮流能蕴藏量341.2~391.9 MW,理论装机容量达1305.1 MW。Based on ROMS(Regional Ocean Modeling System),a high-resolution numerical model was developed for the Zhoushan Archipelago.Validation result suggested the tidal dynamics in this region is well characterized by the model.The simulation results are used to analyze the tidal current power density distribution,operation hours and flow stability,and to calculate the reserves and installed capacity of six tidal energy abundant channels.The results show that the most tidal energy resources in the study area are distributed in six channels,such as Luotou,Xihoumen and Guishanhangmen,with the peak power density of high tide exceeding 25000 kW/m^(2) and the stability coefficient of flow direction greater than 0.95.The area of the Class Ⅰ Zone is 7.77 km^(2),the area of the Class ⅡZone is 41.99 km^(2),the tidal energy reserves are 341.2-391.9 MW,and the theoretical installed capacity is 1305.1 MW.
